- * extra work of storing the value doesn't count, since a delay is
- * needed after a SCC access anyway. Additionally, _SCCwrite() manages
- * writes to WR0 and WR8 differently, because these can be accessed
- * directly with less overhead. Another special case are WR7 and WR7'.
- * _SCCwrite automatically checks what of this registers is selected
- * and changes b0 of WR15 if needed.
- *
- * _SCCread() for standard read registers is straightforward, except
- * for RR2 (split into two "virtual" registers: one for the value
- * written to WR2 (from the shadow) and one for the vector including
- * status from RR2, Ch. B) and RR3. The latter must be read from
- * Channel A, because it reads as all zeros on Ch. B. RR0 and RR8 can
- * be accessed directly as before.
- *
- * The two inline function contain complicated switch statements. But
- * I rely on regno and final_delay being constants, so gcc can reduce
- * the whole stuff to just some assembler statements.
- *
- * _SCCwrite and _SCCread aren't intended to be used directly under
- * normal circumstances. The macros SCCread[_ND] and SCCwrite[_ND] are
- * for that purpose. They assume that a local variable 'port' is
- * declared and pointing to the port's scc_struct entry. The
- * variants with "_NB" appended should be used if no other SCC
- * accesses follow immediately (within 0.5 usecs). They just skip the
- * final delay nops.
- *
- * Please note that accesses to SCC registers should only take place
- * when interrupts are turned off (at least if SCC interrupts are
- * enabled). Otherwise, an interrupt could interfere with the
- * two-stage accessing process.
